fix: drop region tags chosen by machine model

XRoar reads the Dragon 200-E and Alice ROMs for those machine configs
(src/xroar.c:437-444, 552-558 at 1.12.1), and VICE the Japanese kernal
and chargen for the C64 JAP and VIC-1001 models: a (Japan) file name
selects the NTSC model (libretro-core.c:2018-2034). No code branches on a
territory for these files, so region: is removed, as profiling.md rules
for a model enum.
